When assembling a super-quit PC system there is now way around 2.5" HDDs or even a SSD. Decreasing prices combined with increasing capacity and better access times make the small hard drives the perfect choice for a user wanting to assemble a quiet system. The Twin mounter 2.5" allows installation of up to two 2.5" hard drives or SSDs in a 3.5" drive bay. This means that the system will not only be more quiet, this solution also gives additional space inside of the case!
